To (tZZwhom/ it TIMI/J] concern:

Be it known that I, JADIES HERVA JoNEs, a citizen of the United States, residing in the city of Rockford, in the county of .Vinnebago 5 and State of Illinois, have invented new and useful Improvements in Cultivators, of which the following is a'specification.

This invention relates to that class of cultivators known in the trade as straddle-row 1o cultivators, but more particularly as walking-cultivators, but capable of use as a combined walking and riding machine, in which form I have represented it in the accompanying drawings.

The object of this invention is to produce a cultivator capable of the uses to which such machines are applied, and of a construction such as to render the weight of the frame of the machine available in raising and supporting the shovel-beams, and, when employed as a riding-cultivator, to utilize the weight of the driver to assist in raising and supporting the shovel-beams in their elevated position; and it consists in a novel construction of the car- 2 5 rying-wheel supports made of parts separate from the parts usually known as the arch-bar axle-tree; in a novel connection of the carrying-wheels with the main frame in a manner to permit a limited vertical movement of the frame independent of the carryingwheels; in a novel lever having a pivotal connection with the wheel-support, the main frame, and alink connection with the shovel-beains, to utilize the weight of the main frame in raising and 3 5 supporting the shovel-beams; in a novel connection of the shovel-beams with the main frame; in a novel locking mechanism to hold the shovel-beams suspended in transit, and in a novel-safety slip-tooth mechanism. These and other novel features, the necessary devices and their several combinations, all of which will be hereinafter more fully described, constitute the subject-matter of this specification.

In the drawings, Figure 1 is a plan view of 5 acultivator embodying my invention, of which Fig. 2 is aside elevation, in which one wheel is omitted, and the shovel-beams are in their working position; and Fig. 3 is also aside elevat-ion, in which one of the wheels is omitted,

and the shovelbeams are elevated in position for transportation. Fig. 4 is a rear elevation of the right side, with the frame in its lowest position. Fig. 5 is a rear elevation of the left side with frame elevated. Fig. 6 is a length wise vertical central section of the joint-con- 5 nection of the shovellocams with the main frame. Fig. 7 is an isometrical representation of the pivoted lever connecting the supporting-wheels with the main frame. Fig. 8 is an isometrical representation of the safety-slip 6o mechanism employed to connect the shovels to the shovel-beams; and Fig. 9 is an isometrical representation of the pivot-stud support of the pivoted lever, showing its connection with the transverse bar and with the tongue- 6 5 beams.

In this machine the transverse bar, which is usually known as the axle-tree or arched bar, is produced from bar material bent in crank form, consisting of a central horizontal 7o portion; A, vertical arms A. and outwardprojecting horizontal arms A. The tongue consists of two like boa-ins, B, having their forward ends joined to each other and fitted to receive a neck-yoke adapted to connect with the harness of the teamj These beams from their point of connection extend rearward in diverging lines, and their rear end portions are connected to the vertical arms of the crankfornied transverse bar in the inner angles th ereof, formed by the vertical arms and central horizontal portion.

At a are represented caps having their vertical portions semicircular in cross-section, of suitable dimensions and conformation to re coive the upper end portion of the vertical arms of the transverse bar. These caps are provided with ears b, extending from their vertical sides in the lengthwise direction of the tongue-beams. These ears are perforated to receive suitable screw-bolts, which extend through the tonguebeams, and by means of suitable screw-nuts serve to securely fir: the parts in position. These caps are also provided with a stud-journal, c, projecting lat- 5 erally from their lower portions outward, and are also provided with rib-like catch-arms d, formed on their outsides, extending from their upper ends downward toward the stud-like journal; and the purpose of these parts will 10o hereinafter appear. These caps, as will readily be seen, are made interchangeable and caverse bar 0, from which it extends forward centrally between the tongue-beams, and-to its forward end is pivoted an evener, E, having its end portions provided with depending draft-hooks c, the lower ends of which are fitted in hook form to receive the whiffletrees.

At F are represented draft-plates fitted to the lower lateral or horizontal arms, A, of the transverse bar, to which they are fixed by means of a suitable screw bolt, f, passed through the parts, and also fixes the foot of the brace-rod G to the draft-plate. These brace-rods G, from their foot-supports on the draft-plates, extend forward, inclining inward and upward, and meet the transverse draftbeam under the tongue-beams, and are connected therewith by means of the same bolts which fix the draft-bar to the beams.

H represents the free arm of a lifting and holding lever, provided near its end with a transverse socket-bearing, h, adapted to re ceive the stud-journal c of the cap a in a manner to oscillate thereon freely. These levers H are provided with an outward-curving arm, h, having their outer end portions, h, fitted in stud-journal form, which are eccentric to the socket-bearing h.

At I are represented axle-supporting bars having their upper ends pivoted on the studjournals h, and their lower end portions fitted to enter and slide vertically in guideways 7:, formed in the outer ends of the draft-plates F.

At 7c are represented axle-arms securely fixed to their supporting-bars I, from which they project outward and are fitted to receive the supporting-wheels to revolve thereon.

At K are represented supporting-wheels mounted on the axle-arms k in a manner to revolve thereon freely. From the construction and arrangement of these parts it will be seen that'if the free arm H of the lifting and supporting lever is turned over forward in the position shown in Fig. 3 the main frame will be in its lowest position, as shown therein; and when it is turned'over in its rearward position, as shown in Fig. 2, the main frame will, be elevated, as shown therein; The rear edge of the draft-plate F is provided with a series of holes, Z, adapted to receive a suitable stud-bolt, employed to connect the shovelbeams with the plate. The stud-joint bolt employed to connect the shovel-beams with the draft-plate consists of a tubular portion, Z, a washer, Z, and a screw-bolt, Z, which receives the'washer and the tubular portion, .and its screw-threaded end is passed upward through the holes Z in the draft-plate, and its projecting end is fitted with ascrew-nut, by

means of which it is firmly clamped in position and is made adjustable in any of the holes Z in the plate.

At m is represented a sector-formed jointsoeket fitted to receive the joint stud-bolt in such a manner as to oscillate thereon in a vertical and lateral plane. The rear end of this joint-socket is fitted with a recess on both sides adapted to receive the forward end portions of the shovel-beams.

At L are represented shovel-beams made from suitable bar material, having their rear ends curving downward. The forward ends of these beams are fixed'to the rear arm of the joint-socket, from which point they extend rearward in diverging lines, and are suitably supported in their relative position by means of transverse stay-bolts a.

At M are represented handles fixed to the shovel-beams by means of the stay-bolts n and additional bolt, it. These handles are employed to enable the operator to control the movements of the shovels.

At N are represented cultivator-teeth of the usual shovel form, fixed in any proper manner to a sleeve, 0. The sleeves to which the shovels are fixed are of a form to embrace the opposite sides of the downturned end portions of the shovel-beams, to which they are pivoted, as at 0. The upper ends of these sleeves are provided with side ears, 0, which rise above the front edge portion of the sleeve.

At P are represented lever f fiction-clamps constructed with jaws 0, which embrace the shovel-beams, to which they are pivoted by means of a suitable clamping screw-bolt, 1), passed transversely through the parts. The position of these pivoted jaws relatively with the sleeve are such that when the parts are in their working position their depending hook ends will engage the side ears of the sleeves, and the free arm of the lever-clamp will be turned up against the rear curved edge of the shovel-beam, as shown in Figs. 2 and 3. WVith these parts in their working position the jaws of the lever are clamped to the shovel-beam by means of the pivot clamping-bolt with a force sufiicient to hold the shovels for the purposes of cultivation, but in sucha manner that, the shovel meeting with an obstruction offering a resistance to endanger the safety of the shovel, the friction mechanism will. render or give way, and permit the shovel to turn backward and the parts to assume the position represented in the dotted lines, in which position the shovels will override the obstruction without injury; and after the obstruction has been passed, the operator, by means of the free arm of the lever, can return the parts to their working position without the aid of tools.

At R are represented suspension-rods hav-' ing a suitable link connection at their rear ends with the shovel-beams, and at their for- Vhen the shovels arein 'tion.

their working position, as represented in Fig.

2, the free end of the lifting and holding lever,

ency will. be increased by reason of the changed position of the parts in thcoperation, and when the parts have assumed the position represented in Fig. 3 their relative position will be such as to hold the shovel-beams elevated in a suitable manner for the purpose of turning at the ends and getting the machine in position to be employed for the purposes of cultivation, but in such a manner as to permit the beams to be lowered to their working position by a slight downward pull upon the handles. The outer curve of the arms h of the lifting and holding lever relatively with the catcharin d of the caps a, is such that when the shovel-beams are in their elevated position the suspension-rods will be carried by the curve of the arms h under the catcharms cl, to prevent the accidental dropping of the shovel-beams.

At s are represented hook-bolts, which extend upward through the rear extensions, t, of the lifting and holding levers, in position to permit their hook ends to be turned over thesuspensionrods to securely hold the shovelbeams elevated for the purpose of transporta- By this construction and arrangement of the parts I produce a cultivator in which the weight of the main frame is utilized to as sist in raising the shovel-beams, and when raised to hold them suspended, for the purpose of handling the machine when used in cultivation, and in such a manner that they may be lowered to their working position by a downward pull on the handles. This construction and arrangement also enable me to produce a cultivator in case of handling with in the capacity of boys unable to handle eultivat-ors as ordinarily constructed.

At l3 is represented a seat-support consisting of a wooden beam rectangular in sec; tion and of suitable dimensions. The forward end of this beam is fixed centrally to the transverse beam C, which connects the tongue-beams, from which it extends rearward under the central horizontal portion of the transverse bar, at which point it is fixed to the axle-tree by means of a screw-hook or staple-bolt, a, which spans the axle-tree, and its screw-threaded arms extend through the seatsupport and are fitted with screw-nuts,

' by means of which the parts are securely held in place.

At T is represented a drivers seat, fixed on the rear end of the seat-support. This seat is so located relatively with the axle-tree and with the shovel-beams that when the driver is mounted thereon his feet will engage the shovel-beams, to enable him to impart the use cssary lateral movements to the beams to direct the line of travel of the shovels.

The seat and seat-support are designed to be employed when my improved machine is constructed as a. com bined riding and walking cultivator, and also when constructed as a riding-cultivator, and in both instances the seat is supp ortcd on the main frame, which enables me to utilize the weight of the driver to assist in raising the rear ends of the shovel-beams from the ground when desired.
